This is all great info.The new hardware and software went into production 11/19; issues from then to current production 2023 models are extremely uncommon. The production and service parts are the same.
You got the new hardware but they didn’t install the new calibration. Hence the repeat issue. If they had done the recall it’s very unlikely you’d be in this situation. Make that clear to the dealer; they caused a repeat failure of the parts they installed due to their negligence.
FYI - The discrepancy in the dates for 21B10 is due to an extension in the program. It was originally supposed to expire Feb 2022 but it was extended to July 2022.
The discrepancy in the dates isn’t about 21B10. It’s about 21N03.
I am of the understanding that if a customer got 21B10 done on March 1st 2022 they got zero coverage afforded to them through 21N03. Please correct me if I’m wrong.
I understand the program has since expired but that could give them an excuse as to why they didn’t do it?
Since I wouldn’t have got any extended coverage in April of 22?
I am also of the understanding that the new parts came substantially before the new software of 21B10. 21B10 supplement 1 wasn’t released until March 2nd of 2021.
Almost a full year after I had my phasers “fixed” with the new hardware.
Meaning my phasers were improperly wearing for a year before the software was ever released?
And then supplement 2 and 3 just extended the dates? I’m assuming there isn’t a supplement 4?
Am I correct in thinking that the new software didn’t come out until March of 21?
Meaning when the dealership did the actual phaser repair in April of 2020 no new software existed?
Still doesn’t change my argument that it for sure existed in April of 22 as a mandatory recall that should have been done even if I didn’t get the extended benefits of 21N03
